Beta.ray – Spherical Collector That Combines Photovoltaic and Thermal Power

beta-ray-generator

Problem:

  • Solar panels are generally fixed and their optimal collection is limited due to collection angle.
  • Cloudy days traditional solar panels are inefficient in collecting sunlight
  • Solar panels take up a large amount of space.

Solution:

  • Most solar panels are fixed direction, the beta.ray can rotate according to the sun direction, maintaining optimal collection angle – the small sphere, 75% smaller than a panel that collects the same amount of energy.
  • Cloudy days the beta.ray can improve efficiency by 50% due to concentration of sunlight.
  • The beta.ray is small and can be placed on any flat surface.
  • The spherical shape of the solar collector, together with an integrated solar tracking system, cover far smaller surface area than solar panels of equal efficiency, and allow a collection of energy, even if the light is very low
  • The transparent crystal lens that works as a concentrator of incoming light, Rawlemon’s design promises as much as 95% more energy conversion

Solar Powered Aircraft

1) Energy & Waste: The aircraft industry contributes to 9% of the total CO2 emissions among the transportation sector in the United States. These emissions are expected to triple by 2050 without the establishment of policy regulations. Ultimately, alternative sources energy and a transition away from harmful pollutants into the atmosphere need to be developed to align environmental concerns with transportation demands. As such, Solar Impulse has developed to fully solar power aircraft to tackle the issue.

2) Technology:

  • The project took 12 years of research and development to come to fruition, resulting in a 2.3 ton aircraft with over 17,000 solar cells (23% energy efficient) that were each tested 3 times
  • The PV cells are protected from UV radiation with a polymer film and many of the components are made with carbon fiber and alveolate foam in a honey comb structure
  • It consists of multiple lightweight characteristics such as led lights and structural components, solar cells, energy dense batteries, energy efficient electric motors (97% efficient), and thermal insulation
  • The aircraft has the capacity for only one pilot at a time and is composed of an unheated and unpressurized cockpit measuring 3.8 cubic meters

3) Organizational Stakeholders:

  • Engineers and designers at Solar Impulse
  • Aircraft carriers
  • Customers for transportation needs (potentially)

4) Deployment:

  • Conduct further test runs of the technology to boost accuracy and make improvements
  • Invest in more R&D and materials evaluations for increase the size/capacity of individual aircrafts
  • Incorporate innovations in battery storage and solar energy conversion to drive efficiency and product reliability

Comments to Off grid solar powered water device – Zero Mass Water by JV2610

  • A unit with one solar panel, the company says, can produce two to five liters of liquid a day, which is stored in a 30-liter reservoir that adds calcium and magnesium for health and taste. This seems very energy efficient and seems to be able to store a pretty good amount. The addition of electrolytes is even more interesting and beneficial for health.

Dirty Clothes and No Grid Access? No Problem!

Sustainability Technology: Yirego Corporation has developed a quick way to do laundry without using electricity.  With a holding capacity of up to 2kg (4.4 pounds), the Drumi, can do a load of lightly soiled clothes within about 5 minutes.  Pedal operated, the Drumi can handle 5L of water for each load.

Sustainability Issue: An estimated 1.2 billion people or 16% of the global population do not have access to electricity and most of them live in rural areas in sub-Saharan Africa and developing Asia meaning without a significant change in infrastructure, they are unlikely to get grid access any time soon.  Doing laundry in the developing world is very time consuming and takes a lot of physical energy as well.  The laundress (or launder) has to find a water source, soak then scrub the clothes, wring them dry, and carry the clothes back to be dried out in the sun.  On top of all this, the harsh scrubbing process can compromise the structural integrity of the clothes being washed.  The Drumi drastically cut down on the time and physical activity.  The water can be collected separately, which is probably already a daily task, and the cleaning can be done at home.  With just a 5 minute cycle, approximately 5-6 loads (including hanging) can be done in one hour. Admittedly, the Drumi, at $140 is probably too expensive for some households, and financing would most likely be necessary, but a cost benefit analysis would likely show that it is a useful investment.

Sustainability Stakeholders: 

  • Families with limited or No Access to the Grid
  • Launders/Laundresses in Developing countries
  • Developmental Organizations
  • Rural Communities
  • Avid Campers
  • Mobile Home Residents
  • Urban Residents without Washer/Dryer

Implementation Steps:

  • Research a community in sub-Saharan Africa with a need for a better laundry system.
  • Find funding through a development grant using the research as a basis for need.
  • Establish a public/private partnership with Yirego
  • Work with local community and establish a working partner in region who can train, maintain, and distribute Drumi systems to families in the region.
  • Offer a financing package through the grant and private partnership
  • If successful, create the same model with other developing communities.

Mobility for Disability

Sustainability Problem:

There exists a need for artificial muscles that are silent, soft, and compliant, with performance characteristics similar to those of skeletal muscle, enabling people to overcome their disabilities. Different types of electric motors or pneumatic systems drive exoskeletons, prosthetic and assistive devices to enhance human performance or aid disabled people to walk and carry out everyday tasks. They provide fast responses but are bulky, heavy, stiff, noisy, non-biological in feeling, and as such less accepted by the end user.

Technology:

  • Textile processing permits scalable and rational production of wearable artificial muscles, and enables novel ways to design assistive devices.
  • Swedish researchers have created actuators (An actuatoris a type of motor that is responsible for moving or controlling a mechanism or system)— from cellulose yarn coated with a polymer that reacts to electricity. These fibers are then woven and knitted using standard industrial machines and coated with conducting polymers using a metal-free deposition. The researchers have called these textile actuators, “textuators”.
  • These textuators scale up force by parallel assembly of single fibers (Fig A), amplify the strain by using stretchable patterns ( B), and can be effectively mass fabricated. This will allow for a new means of driving and designing assistive devices, such as exoskeleton-like suits with integrated wearable actuators.

Stakeholders:

Hospitals, NGOs caring for disabled people, People with temporary or permanent disabilities, Elderly people, Prosthetic industry, Physiotherapists, People recovering from injuries etc.

Implementation:

Knitting and weaving artificial muscles could help create soft exoskeletons that people with disabilities could wear under their clothes to help them walk. By varying the processing method and the weaving pattern, it should be possible to tailor the force and strain characteristics of a textuator to the specific application at hand.

How does it reduce disease? Can this technology be also used to store grains?

Blockchain Peer Peer Energy Microgrid

Infrastructure Problem: Renewable Energy From microgrid can be wasted due to inefficient data and demand

Solar panel owners get a small return for feeding excess power from their roof back into the grid, which power companies then on-sell at a much higher price.  Peer-to-peer trading overhauls the system by opening up the market to allow households to buy and sell solar energy without a power company, trading their energy for more than the feed-in tariff while still undercutting power providers for buyers.

Infrastructure Technology:

Power Ledger has developed software which reads the outputs of electricity meters and can therefore measure the amount of energy that is consumed or generated. Power Ledger is a blockchain-based peer-to-peer energy trading platform enabling consumers and businesses to sell their surplus solar power to their neighbours without a middleman.

Those two pieces of information are then recorded on the Blockchain and used to move energy from one person to another via a unit called ‘Sparkz’, which is a digital representation of energy. The buyer receives the energy and the seller banks payment for the electricity almost simultaneously

The Power Ledger system tracks the generation and consumption of all trading participants and settles energy trades on pre-determined terms and conditions in near real time. A user simply receives a registration email from their Application Host, they click on a link which takes them to the Power Ledger platform where they create a userid and password. That’s it, once logged in they can see their electricity usage and all their P2P trading transaction details.
